Here's something I was thinking about the other day. I *know* for a fact that SCSI
interface hard drives existed with 8" platters. I've never seen one, however.
Does anyone know of any specific model numbers, or have any product information or
pictures of such devices?
Along the same lines, did SCSI interface devices exist with 14" platters? An option
for the venerable Fujitsu Eagle, perhaps?
I know that Adaptec made a standalone SCSI-SMD bridge board. I have one, although I've
never been able to get it to work. I got as far as hand-crafting SCSI commands to try to
get it to format the drive, and it would sit there, device active, but the drive never
stepped or seeked off the first cylinder.

Interesting question, I've never seen any sign of 8" SCSI drives. I
have some DEC 8" RA series drives, they're the largest physically
that I own (I don't have an RA8x drives).
The largest SCSI drives I've ever seen were 5.25" full-height. I've
also seen ESDI drives with SCSI converters. Even early on, many of
the SCSI HD's were 3.5", so I've always thought of the 5.25"
full-height drives as the large form factor.

I wonder if it needs some vendor-specific command to define the attached drive
geometry before it'll do anything? Lots of old SCSI-to-something converters
worked that way. (Does it support - and return something sensible for - the
Inquiry command? Some converters did at least respond to that without any
initial setup, and it'd at least indicate that your board's partially
operational and listening)

Fujitsu made SCSI-variants aside from their long-lasting 8-inch disk drives.
They basically hat an SMD-E to SCSI bridge added. I am in posession of a
M2333K-drive with such a bridge-board made by Fujitsu. The drive has the
model-number M2333KS and has a capacity of 330MB.
